o all whom, it may concern:

Be it known that I, Guan ne 0. Hints, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State of Indiana have invented a certainnew and useful hadiator-Cap; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawcaps upon the radiator.

'erein metal caps having laterally extendin arms or mountin s of various types,-

it has een dificult to tig tly screw them on to the radiator so that the arms or mountings will bein proper position, or when the arms or mountings are adjusted in proper posi tion, the cap is often notscrewed on tightly enough, thereby permitting leakage. By means, of. this invention it is made possible to so adjust the threaded portion of the cap therein that it may be screwed tightly upon the radiator withthe arms or mountmgs in their proper position.

- Another feature of the invention lies in the construction of the cap, whereby a shell or the threaded portion of an old cap may be readily and quickly inserted in any metal housing and adjustably secured therein, so that the cap maybe screwed tightly on the radiator with the fittings in proper position. This arrangement enahles a single casting or die for: the metal portion ofthe cap to be used for nearly all sizes'of radiator openings, so that such caps may be manufactured and sold considerabl cheaper than a cap specially made for t e particular opening.- .ihis feature ofthe construction also enahles the purchaser who desires a metal ca Ell) of .the particular design to purchase a Stan ard casting andfit it to his old radiator cap which would greatly reduce the cost of hai ing made or purchasing a cap of special size to fit his particular ra iator.

Another feature df the invention is the einhodimentof a lock on the-periphery of the radiator cap, whereby it may be looked upon the radiator for preventing theft of the cap orthe mounting thereon. Where's articularly attractive and well made cap is mounted upon the radiator with a moto meter or other mounting therein, the value thereof and the ease of removing it often results in its theft from. the automobile, and it is the feature of this invention to protect the same from such theft by means of a lock. The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings, Figure 1 is a front elevation of a radiator cap with mountings, showing a central vertical cross section through said cap. Fig. 2 is a plan view ,looln'ng down on said cap and radiator. F 1g. 3 is a cross section through a portion of the cap showing the lock therefor. Fig. 4c is a section through a portion of the cap and radiator neck showing a modified form wherein said neck is provided with screw threads on the inside thereof. Fig. 5 is.

a .plan view showing the locking collar mounted about the neck of the radiator. Fig. 6 is a central vertical cross section through a modified form illustrating a Ford radiator cap with an auxiliary cap adjustably mounted thereon. Fig. 7 is a plan viewof the auxiliary cap.

In the drawings there is shown a radiator cap t0 adapted to be screwed upon the open ingin the top of the radiator 11. Said cap I is comprised of a casting or stamping" embodying, integral therewith, the outwardly extending arms 12,, or: other mountings or fittings, such as Wings, ornaments or a motometer 13, as shown herein. The casting is} provided with the projections 14.- extend ing radially inward, as shown in Fig. 2. The casting or stamping 10 may he formed and sold upon the market together with a plate 15 adapted to fit snugly within the top of the cap and engage the projections 14 so as to prevent it from turning therein. A-holeor opening 16 is provided through the center of the cap and plate. The screw threads for securing the cap upon the neck of the radiator opening are provided by the metallic threaded inserts of any cap,

and pa'rticularly those used with hard ruleber. The hard rubber is removed from the :metal insert,or metal inserts may he manu= factured forthis' express purpose, and secured to the-metal cap in the following manner:

. The method of adjusting nd mounting the screw threadedinsert to t e cap, whic is one feature of this invention, is as follows. The insert 17 is first screwed on to the neckof the radiator as tightly as possible.

The plate 15, which is provided with the screw holes 18, is then placed upon the top of the insert and adjusted thereon so that the toothed periphery will engage the projections 14 and lie in the proper and desired position, as shown in Fig. 2. The insert is then marked through the holes 18 and removed from the radiator, and the plate 15 secured thereto by screws, rivets or the like in the proper position so marked. If the insert does not have a hole corresponding to 16 already formed therein, such a hole is drilled centrally thereof so as to coincide with the hole 16 through the cap and plate. The bolt on the motometer 13, or any other mounting, is inserted through the hole and secured therethrough by the nut 19. If no ornament or motometer is provided, said members may be secured together in any suitable manner, such as by means of an the appearance or the functioning thereof.

It is also not necessary to rivet orfirmly secure the insert to the plate 15 as long as there are means for holding these two in their respective positions. This may be accomplished by means of pins or projections cast or stamped upon the under side of the plate 15 and extending into depressions or holes made in the insert after the two are properly adjusted on the radiator. It is also immaterial as to the position of the threads upon the insert and the neck of the radiator, as upon similar radiators, the screw threads are on the inside of the neck and on the outside of the cap or insert in this case. In that event, the radiator cap 10 will surround the neck of the radiator which will extend between the periphery of the cap and the insert, as shown in Fig. 4.

The locking feature of the invention consists of a barrel 21 formed integral with the outer periphery of the cap and extending radially outward therefrom, as shown in Fig. 3, in which is mounted a tumbler lock 22 adapted to be operated by a ke 23. The tumbler lock 22 operates'the bo t 24 extending directly downward so as to engage between two jaws 25' formed on the neck of the radiator in any suitable manner, or mounted thereon by means of a band 26. The band and lock are so arranged that they will be in position to be properly locked when the cap is screwed tightly thereon, this position being determined by the adjustment above described.-

In the modified forms shown in Figs. 6 and 7, an insert member in the form of a Ford radiator cap 17 is shown with a radiator cap 14 mounted thereover for improving the appearance, afi'ording the arms 12 for removing it, and permitting of the adjustability above described. The insert member, or Ford radiator cap 17, as is Well known, is provided with four upwardly extending ears 27, and in this instance the cap 14 is provided with eight corresponding recesses 28 cast in the top thereof. A central hole is bored through the member .17, and it is then screwed tightly on the radiator neck 21, the cap 14 is then placed over it so that the arms 12 lie in their proper position. The cars 27 will coincide with and engage in the recesses 28, and the bolt 20, or motometer, will then be inserted through the central hole in both cap and member and tightened up so that they will be locked together as a single cap.

The invention claimed is:

1. The combination with a radiator cap for an automobile having amounting thereon, of means for adjustably securing said cap to said radiator, whereby said mounting will be properly positioned with respect to said automobile and radiator, including a threaded insert member adapted to be screwed upon said radiator, and means for rotatably adjusting and securing said insert member within said'radiator cap in fixed relation thereto.
